Functionalizations of Mixtures of Regioisomeric Aryllithium Compounds by Selective Trapping with Dichlorozirconocene
The reaction of mixtures of aryllithium regioisomers obtained either by directed lithiation or by Br/Li exchange with substoichiometric amounts of Cp2ZrCl2 proceeds with high regioselectivity. The least sterically hindered regioisome

Modulation of (non)linear optical properties in tripodal molecules by variation of the peripheral cyano acceptor moieties and the π-spacer
A series of twelve tripodal push-pull molecules with a central triphenylamine donor and peripheral cyano substituted acceptors has been prepared. These molecules possess systematically altered π-linkers as well as cyano acceptors. Based on the experimental properties measured by differential scanning calorimetry, electrochemistry, one and two photon absorption/emission spectroscopy, supported by the DFT calculations, thorough structure-property relationships were elucidated.

Directed Ortho Lithiation of Isophthalonitrile. New Methodology for the Synthesis of 1,2,3-Trisubstituted Benzenes
The lithiation of 1,3-dicyanobenzene with lithium diisopropylamide occurs in high yield, regiospecifically at the 2-position, to give aryllithium species stable at temperatures below -90 deg C.
